This section explains how to create matrices in the Main application, and how to perform 
basic matrix calculations.

•  Since a vector can be viewed as 1-row by 

-column matrix or 

-row by 1-column matrix, this 

section does not include explanations specifically about vectors. For more information about 
vector-specific calculations, see the explanations about the applicable [Action] menu items in  
“2-8 Using the Action Menu”.

You can use the  (math) keyboard to input matrix values in a single line in the work 
area, or the  keyboard to input matrix values using an actual on-screen matrix.
